Developing Stable, Redox-active, Porous, Organic Polymers for Energy Storage
Abstract
Currently, rechargeable lithium-ion batteries (LIBs) are an important technology in energy storage since they can help with constant energy supply. Traditional battery electrodes have been made of transition metal oxides such as LiCoO2, LiFePO4, and others; however, concerns have been raised about their high toxicity, low recyclability, and restricted availability. Therefore, batteries based on earth-abundant materials are being investigated as more sustainable alternatives. In specific cases, porous organic polymers are a class of materials that have recently attracted attention as substitutes due to their affordability, sustainability, and limitless molecular design. However, a handful of porous organic polymers for energy storage is demonstrated in the literature. As a result, designing and straightforward synthesis of highly performing organic electrode materials to achieve good capacities and cycling stabilities remains challenging and thus highly desirable. In this proposal, the investigators are seeking to design and develop facile method for accessing organic-based electrode materials using porous organic polymers from easily available precursors. Activities in this project would include the design, synthesis and characterizations of new porous organic polymers that contains triangular-shaped phloroglucinol and linear-shaped dianilines along with their applications as electrode materials in LIBs. In addition, the project will engineer porosity of porous organic polymers through the utilization of different linkers to effectively store lithium ions. Furthermore, the modular synthesis of these redox active polymers does not only enable us to customize their physicochemical and electrochemical properties at the molecular scale, but also provide a guideline for improving the performance of the materials for an energy storage application.
